A new method of solving the important problem in ocean optics-the radiative transfer is presented. This method is different from that of tra.ditional ocean optics. We initiate tile transform radiative transfer model as well as concept, theory and research method of information transmission and apply them to the study of radiative transfer in the ocean to overcome difficulties in solving tile integro-differential equation of radiative transfer. By using the optical information processing and linear system theory, the optical transfer fuuetion of the sea water body concerning the image transmission in water, the narrrow-light beam transmission with relation to the ocean lidar, the inverse problem of radiative transfer related to ocean optical remote sensing, the characteristic distribution of the light field in deep sea, etc. have been concisely solevd. Meanwhile, we propose the method of optical informntion processing for the experimental measurement in ocean optics. As a result, the measurement of small-angle (0.05

A multichannel optical Fourier transform has been proved to be a useful method for encoding spatial-frequency or density pseudoeolor[1]. The method of image-processing is accomplished by spatial-filtering the various time frequency channels. Compared with the Ronehi grating methods[2], this method has the advantages of high utilization ratio of light source, has no image resolution loss caused by grating sampling and does not require Fourier transforming lenses of large relative aperture.
